Natural resoucesNatural resorces Extraction involves any activity that withdraws resources from nature. This can range in scale from the traditional use of preindustrial societies, to global industry. Extractive industries are, along with agriculture, the basis of the primary sector of the economy. Extraction produces raw material which is then processed to add value. Natural resources can add substantial's to a country's wealth, however a sudden inflow of money caused by a resource boom can create social problems including inflation harming other industries and corruption.DepletionThe depletion of natural resources is caused by 'direct drivers of change such as Mining, petroleum extraction, fishing and forestry as well as indirect drivers of change such as demography, economy, society, politics and technology. The current practice of Agriculture is another factor causing depletion of natural resources. For example the depletion of nutrients in the soil due to excessive use of nitrogen and desertification. The depletion of natural resources is a continuing concern for society. Protection In 1982 the UN developed the World Charter for Nature in which it recognised the need to protect nature from further depletion due to human activity.The World Ethic of Sustainability, developed by the IUCN, WWF and the UNEP in 1990, which set out eight values for sustainability, include the need to protect natural resources from depletion. It is an interdisciplinary subject drawing on sciences, economics, and the practice of natural resource management.[The term conservation biology was introduced as the title of a conference held University of California at San Diego in La Jolla, California in 1978 organized by biologists Bruce Wilcox and Michael Soulé.

renewableA renewable resource is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere. A positive life cycle assessment is a key indicator of a resource's sustainability. Examples: WoodWind Solar power Hydroelectric powernon-renewable A non-renewable resource is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human timeframes. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. Fossil fuels , and certain aquifers are all examples of non-renewable resources. Examples: Coal Petroleum Natural gas Nuclear fuelManagement Is a discipline in the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations.Management of natural resources involves identifying who has the right to use the resources and who does not for defining the boundaries of the resource.What is a natural resource? Natural resources are derived from the environment. Some of them are essential for our survival while most are used for satisfying our wants. Natural resources may be further classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment.Extraction
